DR DOS Configuration files

12/26/91

Description:

These are some sample configuration files to help you decide how
best to set up your system. It is not necessary for you to use
them exactly as written but they can be used to give you ideas
on what can be done with DR DOS 6.0. What your computer can
actually accomplish is dependent on the hardware of your system.


        PC / XT Computers 640K (only)

DISKMAP C:

These files will setup an XT-type computer to use the following
DR DOS 6.0 features:

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked.

The DISKMAP command takes a snap-shot of Drive C:'s file
allocation table. In the instance of serious disk or file
corruption problems this feature will aid in the recovery of
your disk and files. This command, however, can be executed as
many times as needed during your computing session in order to
get the most recent FAT image (via the $x variable in PROMPT,
see page 294 of the DR DOS manual).

Depending on the use of this type of configuration, this PC/XT
could be used for other "light-duty" services on networks, et
cetera, and therefore, other drivers can be implemented which
would take more conventional memory such as SuperStor'ing the
hard-disk for additional document storage for a printer server.
SuperStor would take about 50K of conventional memory to run,
and could have a serious impact on the ability to run some DOS
applications. The examples for SuperStor in this document are
for drives other than C:. If C: is compressed SuperStor will
create a DCONFIG.SYS file on the uncompressed side and will
place the SuperStor driver there. Refer to Document 1200 for
more information on SuperStor.

An XT-type computer, with LIM 4.0 expanded memory, will take
advantage of the following DR DOS 6.0 features:

First, the computer's expanded memory driver is loaded (named
REMM.SYS in this example). The driver supplied with your
computer will probably be named something different, however,
specify the use of this driver in the same location.

Second, the MemoryMAX driver HIDOS.SYS allows the operating
system to relocate into Upper Memory via the /B=AUTO switch. The
other switches, /CHIPSET=EMSALL or EMSUMB, allow either all the
Upper Memory (128K) to be used for the operating system's
purpose (but with no LIM support) or to allow an EMS page frame
(LIM support) and an Upper Memory Block of 64K. The EMS memory
manager and hardware must be LIM 4.0 compatible for this to
properly work.

The Compressed Disk driver, SSTORDRV.SYS, could be used to
access leftover disk space on another fixed disk partition.

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked or saved. The DISKMAP
command takes a snap-shot of Drive C:'s file allocation table
and will further increase chances of a successful file
"undeletion".

This basic setup is similar to an XT with 640K RAM and
additional LIM 4.0 expanded memory. 

The LIM 4.0 Expansion Board will be outfitted with some amount
of memory and they will come with a device driver which enables
it to work and function with DOS applications. The device driver
that the memory expansion board comes with could be named
REMM.SYS. Please read your documentation for your memory
expansion board for the location and name of the driver that
enables that memory. If the driver supplied with your computer
is named differently, you can still specify the use of this
driver in the same location as indicated by the REMM.SYS line
above.

The MemoryMAX driver HIDOS.SYS is allowing the operating system
to relocate into High Memory via the /B=FFFF switch. You must be
able to configure at least 64K of extended memory at FFFF
(decimal 1Meg) for this option to work. Otherwise, you can use
/B=AUTO.

The other switches, /CHIPSET=EMSALL or EMSUMB allow either all
the Upper Memory to be used for the operating system's purpose
or to allow an EMS (LIM) page frame as well as an extra portion
of upper memory. As stated earlier the EMS memory manager and
the LIM hardware must be LIM 4.0 to work properly.

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked (the tracked being saved
in a hidden file of the same drive). The DISKMAP command takes a
snap-shot of Drive C's file allocation table.



        286-Based Computer with Special Chipsets and Extended
        Memory

These files can be used if your 286/AT has been manufactured
with special ROM chips which offer control of certain memory
functions (page 418-423). These systems offer favorable upper
memory support for DR DOS's MemoryMAX software to enable and use
Upper Memory for TSR's and device drivers. Shadowing should be
enabled in the computer's CMOS to support the creation of upper
memory by DR DOS 6.0.

The important line in this example is the MemoryMAX driver
HIDOS.SYS. This allows the operating system to sense the type of
chipset within the 286/AT, enable Upper Memory and relocate the
operating system files into Upper or High  Memory via the /B=
switch. The valid switch options for /CHIPSET= are:

EMSALL
or              (for 286s with LIM 4.0 compatible
                hardware/drivers)
EMSUMB

NEAT            (for 286s with Chips & Technologies NEAT, NEATsx,
                LeAPSet, or LeAPSetsx)

SCAT		(for 286s with Chips & Technologies SCAT chipset)

RAM             (for permanent Upper Memory. Must be used with
                the /USE option on the HIDOS.SYS driver)

NONE		(for telling HIDOS.SYS not to use Shadow RAM)

AUTO		(for AUTO detection of chipset installed)


        386/486 Based Computers with 1 Megabyte of RAM

DISKMAP C:
:DRDOSEND

This configuration will allow a 386 or 486 based computer to
relocate the operating system into High Memory and enable the
use of Upper Memory. With an average of 120K of RAM in Upper
Memory, one can put network and other drivers, as well as TSR
programs, into that 120K space by using HIDEVICE, HIINSTALL or
HILOAD (for TSRs).

The SuperStor driver is useful in doubling the apparent capacity
of the disk partition to which it's applied. If this has not
been applied to your disk drive, you can elect not to use this
driver and therefore save a substantial amount of conventional
memory. Therefore, the "?" allows the driver to be loaded at
will, whenever that particular partition needs to be accessed.
If the driver is loaded, you can expect to achieve about 603K of
conventional memory. The above example is for a drive other than
C:. If C: is compressed SuperStor will create a DCONFIG.SYS file
on the uncompressed side and will place the SuperStor driver
there. Refer to Document 1200 for more information on SuperStor.


        386/486 Based Computers with GREATER than 1 Megabyte
        of RAM

This configuration will allow a 386 or 486 based computer to
relocate the operating system into High Memory. With an average
of 120K of RAM in Upper Memory, a portion of the SuperStor
driver, the IPX and possibly the NET3 (or NETX) software will
also fit into Upper Memory.

The SuperStor driver is useful in doubling the apparent capacity
of the disk partition to which it's applied. If this has not
been applied to your main disk drive, you can elect not to use
this driver and therefore save a substantial amount of
conventional memory. Therefore, the "?" allows the driver to be
loaded at will, whenever that particular partition needs to be
accessed. The above examples have been for drives other than C:.
If C: is compressed SuperStor will create a DCONFIG.SYS file on
the uncompressed side and will place the SuperStor driver there.
Refer to Document 1200.


        386/486 Based Computers with greater than 1 Megabyte of
        RAM running TaskMAX

CONFIG.SYS

SHELL=C:\COMMAND.COM C:\ /P /E:512

HIBUFFERS=20
FILES=30
FCBS=4,4

if "%delw%"=="on" DELWATCH C: /M:200 
DISKMAP C:
:DRDOSEND

This minimal configuration will allow a 386 or 486 based
computer to relocate the operating system into Upper Memory.
Although this is not optimal for the EMM386.SYS driver, the
amount of memory available on most 386/486 computers will allow
the Upper Memory to be addressed and used for the relocation of
the operating system files, drivers or TSR's. With an average of
120K of RAM in UPPER Memory, the operating system will be able
to get SHARE into HMA, TaskMAX and the Netware drivers into
UPPER Memory. Before Netware is loaded you should be able to
have 625K available conventional memory. Alternately, you can
load the drivers in the AUTOEXEC file from the command line (eg.
SHARE, TASKMAX, HILOAD IPX and HILOAD NETX). 

The NETX utility found on the last DR DOS 6.0 floppy disk is
included to allow you to task-switch on the Network. This will
not allow multiple logins. However, it is designed to allow you
to execute more than one on application on the network.

DISKMAP C:

This basic configuration allows a 386 or 486 based computer to
run WINDOWS  in the "enhanced mode" or "real mode". The
EMM386.SYS driver indicates that a LIM page-frame location is
being established by the operating system driver (/F=AUTO). The
amount of memory allocated to be converted to expanded memory is
1024K (/K=1024). The operating system is being relocated to HMA
(/B=FFFF) and the information in the video and system BIOS ROMs
are being "shadowed" to faster RAM (/R=AUTO).If you want more
upper memory you can disable the LIM Page Frame with the
parameter /F=NONE. This will give you an additional 64K of upper
memory but you will not have any EMS. SuperPCKwik is going to be
2 Megabytes insize (/S:2048) and use the extended memory (/EM)
set aside with the EMM386.SYS driver. It will lend approximately
half of its memory for use as XMS memory for WINDOWS. SuperPCK
is using the WINDOWS compatible portion of its driver
(PCKWIN.SYS) so that WINDOWS performance is enhanced because of
better disk performance. With the EMM386.SYS driver, an average
of 120K of RAM may be available to relocate network drivers,
TSRs and other drivers into Upper Memory. This configuration
has been able to provide 625K of Conventional Memory before
WINDOWS is loaded.

SuperPCKwik is going to use all of the extended memory enabled
by EMM386.SYS for caching the disk drive. Half of this amount
will be "lent" to Windows. SuperPCK is using the WINDOWS
compatible portion of its driver so that WINDOWS performance is
enhanced because of better disk performance. This configuration
has been able to provide 625K of Conventional Memory before
WINDOWS is loaded.

A 2 megabyte computer is not the optimal system for Windows in
enhanced mode. System performance may be greatly reduced because
Windows will need to use swap files and no cache can be used to
help accelerate disk I/O.

This configuration will allow a 386/486 with 2 Megabytes to run
Windows in Enhanced mode. Because Windows requires a minimum of
1 Megabyte of XMS this configuration does not use the HMA. The
SHELL statement has the switch /MU to force it to upper memory.
EMM386 is loading the kernel into upper memory with /B=AUTO and
we use BUFFERS (upper) instead of HIBUFFERS (HMA). Finally,
because we need all of the XMS memory available SuperPCK is not
used in this configuration. Start Windows with "WIN /3".
HIDOS.SYS can also be used to replace EMM386.SYS.

                ******************************

MODELS OF CONFIGURATION FILES

The following configuration ideas should be considered advanced
and for those who are interested in more sophisticated
organization of their configuration  and autoexec files.

Only the basic ideas are outlined in each example. The rest of
the file can be  filled in with your own specifications.

EXAMPLE 1 - The use of GOTO in the CONFIG file.

?"Do you want to run QEMM (y/n)? " goto QEMM
?"Do you want to run MemoryMAX (y/n)? " goto DRDOS

:QEMM
DEVICE=c:\QTR_DECK\QEMM386.SYS
DEVICE=C:\DRDOS\HIDOS.SYS /B=FFFF
(additional QEMM driver lines go here...)
goto COMMON

:DRDOS
hidos=on
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO...
....

:COMMON
files=40
hibuffers=20
...


EXAMPLE 2 - The use of CHAIN in the CONFIG file. This example
shows that you can "link" to other files that hold your
configurations for each system "setup". In the following
CONFIG.SYS file, the two lines direct the configuration process
to the files: QCONFIG and MCONFIG.SYS-files. The appropriate
FILES, BUFFERS, etc. information is contained within those files
and not the main CONFIG.SYS file.

?"Do you want to run QEMM (y/n)? " chain=QCONFIG.SYS
?"Do you want to run MemoryMAX (y/n)? " chain=MCONFIG.SYS


EXAMPLE 3 - The following CONFIG file demonstrates the use of
SWITCH/RETURN commands and use of labels. Select the option by
number and continue processing. Notice the use of the ECHO
statement for setting up the menu options.

ECHO =		Choose how much Extended Memory you want to convert
ECHO =		 	to LIM Memory for this session. 
ECHO =
ECHO =          1 (or ENTER)    No LIM Memory
ECHO = 		2		512K of Memory
ECHO =		3		1024K of Memory
ECHO =		4 		2048K of Memory
ECHO =
ECHO =		Make your selection...

SWITCH NOLIM, 512K, 1024K, 2048K
GOTO DEFAULTS

:NOLIM
DEVICE=C:\DRDOS\EMM386.SYS /F=NONE /K=AUTO /B=FFFF /R=AUTO
RETURN

:512K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=512 /B=FFFF /R=AUTO
RETURN

:1024K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=1024 /B=FFFF /R=AUTO
RETURN

:2048K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=2048 /B=FFFF /R=AUTO
RETURN

:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc...


EXAMPLE 4 - The following CONFIG file section shows how
"environment variables" can be set according to the
configuration options one chooses. These variables are passed to
the command processor (COMMAND.COM) where they can be tested and
processed through the AUTOEXEC.BAT or other batch files. The
CLS, CPOS, EXIT and SET commands are featured in this example.

:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc....

ECHO =		Choose which TSRs and Utilities you want loaded 
ECHO =		 	 at BOOT time for this session. 
ECHO =
ECHO =		1 (or ENTER)   	None... just continue
ECHO = 		2	       	Mouse & Cursor Drivers
ECHO =		3 	       	Keyboard "Speeder"
ECHO =		4	       	Novell Network
ECHO =		5              	Done with selections
ECHO =
ECHO =		Make your selection...

:MORE
CPOS 10,33
SWITCH NOTHING, CURSMOUS, SPEEDKEY, NOVELL, DONE
GOTO MORE

:DONE
:NOTHING
CLS
EXIT

:CURSMOUS
SET THINGS=ON
RETURN

:SPEEDKEY
SET SPEEDKEY=ON
RETURN

:NOVELL
SET NETWORK=ON
RETURN

The accompanying AUTOEXEC below picks up the environment
variables.

The AUTOEXEC.BAT file now allows testing of the environment
variables and executes commands based upon the conditionals as
illustrated below:

@ECHO OFF

(Each line is printed on the screen and you are asked to
load/run the chained configuration file. Each configuration file
is a complete CONFIG.SYS-like file complete with all appropriate
options.)

The idea above can be accomplished by making number-selectable
"menu" choices using SWITCH. Note how the "SET environment"
variables can be used and tested for different "autoexec.bat"
files in this example:

ECHO =	1  For Windows Configuration
ECHO =	2  For QEMM Configuration
ECHO =	3  For DR DOS' MemoryMAX Configuration
ECHO =	4  For 386MAX Configuration
ECHO =	5  For no Configuration... just exit
SWITCH win, qemm, memm, 386m, none
:none

set autoexec=norm
exit

:win
set autoexec=win
chain=wconfig.sys

:qemm
set autoexec=qemm
chain=qconfig.sys

:memm
set autoexec=memm
chain=mconfig.sys

:386m
set autoexec=386m
chain=386conf.sys

Autoexec.bat for the above
